Zhao-type Brachydactyly is an autosomal dominant brachydactyly-syndactyly-oligodactyly syndrome caused by mutations of the HOXD13. It is characterized by metaphalangeal shortage of digits 2 and 5 while digits 3 and 4 often show syndactyly. Patients may exhibit a short stature and some other skeletal abnormalities.
